c# - Powershell can't see variables through wcf -

i have powershell script creates azure vm , installs microsoft dynamics nav on server , more. script sets bunch of variables , calls subscripts.

i can call script c# through pipeline , there no problems. virtual machine gets created , everything.

but there major issue if make wcf client , service , service creates pipeline , executes script.

somehow subscripts don't know variables.

in short: how comes script works perfect if call comes directly console program doesn't if call comes through wcf?

ps: not issue concerning rights because wcf service iis hosted , runs under admin account.

this how call script in both wcf , directly project.
